I use Solaris 10 off and on...
Only prob I ever had is, it throws my LCD outta whack.
It's fun and good for a change of pace....
pay close attention when installing and setting up your internet & email.
personally, I like it. It's a bit different but not that hard to get a hang of.

BTW... install on a separate HD as it does not play nice with Linux installs as they share the same I.D.'s
Set it up as the second HD, and then make changes to your bootloader respectively by adding a new stanza in the menu list
